TM and RM air cleaner intake tubes

[LWC82PE]

What is the ID of each end of the following Suzuki air cleaner boot/connectors
Need to know if they will fit 58mm on 30-34 Mikunis plus what size the airbox end is.

They are pretty expensive so I don’t want to buy one just to measure it

I can say yes the Airbox end/ Large is 75mm on the PE175C,N (out of all my RM's and PE's the PE175N is the only one stripped down enough to measure ) I came up with 76mm measuring the O.D of air box but the air box was still in the bike without the airfilter outlet
 to carby tube removed

Yeah it is normal for the airbox to be about a 1mm bigger than the rubber. So 75mm confirms that one ok. Thanks

Just bought one for my 125b $20:60 from Mick Hone in Melbourne??

[LWC82PE]

Thats a good price if i need one. Not sure yet. TM250 or RM125m might be better dimensions for my use.

[TT5 Matt]

what about the ts185 hop up kit intake tube as they used a 30mm carb

[LWC82PE]

Might be an option. Got a part number for it? Just want something that is also readily available too and so far the PE175 one looks like best option in that aspect, but i would prefer a bit smaller than 75mm on the air box side.

I think you will find it will be less than 75mm they are always a stretch to get on despite the retaining lip on the air box (spigot) most of the time I have to heat up ( usually with hot water in a saucepan ) same carby end (but with heat gun on low) with some surface tension releasing agent (I just spray kero it helps get the bastard on and dries with no oily residue) Ive probably gone to far some times and should of bought a new one instead of tinkering, but no crack or splits just a bit hard and slightly shrunk LOL tight ass, I am
(don't worry I do buy new ones and don't use those old all hard and brittle one's)

[TT5 Matt]

part no for the ts185 hop up kit air cleaner to carb pipe is 13881 29700, fits 71 to 74 models
